Need help implementing a pop up to show an ArrayList on a flight arrivals map in Java Eclipse

I have been trying to create a flight arrivals map program using windowbuilder however I have been stuck on displaying in the incoming flights for each airport
For context this map[ should display incoming flights when you hover your mouse on the letters(i.e hovering on YYZ will display incoming flight arrivals for Toronto airport)
I have an set of ArrayLists from a java file. Lets call it Aeroports.java which scans a csv file and scans it adding a line into a certain arraylist depending on its airport code(e.g YYZFlights)
The CSV file is in the format
DateOfFlight[0],DepartureTime1,ArrivalTime2,FlightDuration[3]
I have posted the full code below. I had to change the format of the dat so it could be read
Below is the program which stores the setters(procedures) and getters(functions) for each object
import java.time.LocalDate;
import java.time.LocalTime;
import java.util.Date;
public class Flights {
private String flightNo;
private String departureCity;
private String departureAirport;
private String ArrivalAirport;
private int delayedTime;
private LocalTime newArrivalTime;
private LocalTime ArrivalTime;
private LocalTime departureTime;
private LocalDate FlightDate;
public void setFlightNo(String flightNo)///sets the flightNo for each object
{
this.flightNo = flightNo;
}
public String getFlightNo()
{
return flightNo;
}
public void setdepartureCity(String departureCity)///sets the departure city for each object
{
this.departureCity = departureCity;
}
public String getdepartureCity()
{
return departureCity;
}
public void setdepartureAirport(String departureAirport)///sets the departure airport for each object
{
this.departureAirport = departureAirport;
}
public String getdepartureAirport()
{
return departureAirport;
}
public void setdelayedTime(int delayedTime)
{
this.delayedTime = delayedTime;
}
public int getdelayedTime()
{
return delayedTime;
}
public void setnewArrivalTime(LocalTime newArrivalTime)
{
this.newArrivalTime = newArrivalTime;
}
public LocalTime getnewArrivalTime()
{
return newArrivalTime;
}
public void setArrivalTime(LocalTime newArrivalTime)
{
this.ArrivalTime = newArrivalTime;
}
public LocalTime getArrivalTime()
{
return ArrivalTime;
}
public void setdepartureTime(LocalTime departureTime)
{
this.departureTime = departureTime;
}
public LocalTime getdepartureTime()
{
return departureTime;
}
public void setArrivalAirport(String ArrivalAirport)
{
this.ArrivalAirport = ArrivalAirport;
}
public String getArrivalAirport()
{
return ArrivalAirport;
}
public void setFlightDate( LocalDate FlightDate)
{
this.FlightDate = FlightDate;
}
public LocalDate getFlightDate( )
{
return FlightDate;
}
}
Listed below is the main program where delayed flights are calculated for each object and stores the ArrayLists that I intend to use in the future

In another GUI java program I have used the pop up method to show a window depending on which airport I click on.
lblNewLabel_11 = new JLabel("HND");
lblNewLabel_11.addMouseListener(new MouseAdapter() {
Popup frame = new Popup();
public void mouseEntered(MouseEvent e) {
frame.setVisible(true);
}
public void mouseExited(MouseEvent e) {
frame.setVisible(false);
}
});
lblNewLabel_11.setFont(new Font("Tahoma", Font.BOLD, 10));
lblNewLabel_11.setBounds(817, 277, 27, 13);
contentPane.add(lblNewLabel_11);
lblNewLabel_12 = new JLabel("SYD");
lblNewLabel_12.addMouseListener(new MouseAdapter() {
Popup frame = new Popup();
public void mouseEntered(MouseEvent e) {
frame.setVisible(true);
}
public void mouseExited(MouseEvent e) {
frame.setVisible(false);
}
});
lblNewLabel_12.setFont(new Font("Tahoma", Font.BOLD, 10));
lblNewLabel_12.setBounds(855, 503, 45, 13);

textArea.append(f.getdepartureTime() + " " +f.getdepartureAirport() + " " + f.getArrivalAirport() + " " + f.getArrivalTime() + " " + f.getdelayedTime() + " " + f.getnewArrivalTime() + " " + f.getFlightDate() + "\n" );//prints the results and goes to a new line
}
}
}
The main issue I have having is working out how to implement a way to show the incoming flightArrivals for each airport depending on which aiport I click for a reference see the picture for how the airport UI looksHere's UI normally
When I hover on the name of an airport at the moment blank window pops up but I want it to show the incoming arrivals for the day. I have been able to show delayedFlights but have been unable to show the specific arraylists for each airport which I want to show in the format
ArrivalTime, Departure City, Departure Airport, FlightNo
It should look like this when you hover on a airport nameHow it should ideally look like
If someone could help that would be great becaus I'm quite stuck

What exactly is your issue? Is it that you only see delayed flights but not all flights? You have static ArrayList<Flights> allFlights = new ArrayList<Flights>(); but as far as I see you never add a flight to it. You only add flights to the other lists.
Unrelated to your main issue, but some general observations:
Consider renaming Flights to Flight This class is a single flight, not a list of flights right?
You have an ArrayList<Flight> for every airport. This seems really difficult to work with. Maybe there is a different data structure that better fits your needs. Maybe Map<Airport, List<Flight>> flightsByAirport
It looks like each airport is it's own class? BCLAirport Maybe there is a different way to handle that.

How to display score after a quiz using javax swing?

I am trying to write a program to take a quiz and then display the score at the end of 5 q. But my score always shows 0 regardless of what I do.
I have attached most part of the code so that it can be inserted into an IDE for checking.

the problem is with location of your code:
if (score == 5) {
jscore.setText("******Congratulations!!! A perfect score indeed!!!!!!******");
} else if (score >= 3) {
jscore.setText("You have passed. Your score is : " + score);
} else {
jscore.setText("You have failed. Your score is :" + score);
}
according to your code this section runs only one time and the jscore text does not change after changing the correct answers so I moved this section of your code inside result button to check it after each click of this as:
result = new JButton("Click to see your reportcard");
result.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
cardlayout.show(cardpanel, "4");
if (score == 5) {
jscore.setText("******Congratulations!!! A perfect score indeed!!!!!!******");
} else if (score >= 3) {
jscore.setText("You have passed. Your score is : " + score);
} else {
jscore.setText("You have failed. Your score is :" + score);
}
}
});

Drawing text from keyboard input on a canvas

I want to make a paint program.
When the user clicks the text button, then the user click the canvas the user can input the text they want in the clicked location.
What can I use to make that happen?
When i use drawstring, I can put the pre-defined text and user click location
Graphics2D g2 = (Graphics2D) g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
Font font = new Font("Serif", Font.PLAIN, 40);
g2.setFont(font);
g2.drawString("text", x, y);
How can I change "text" to what the user inputs from keyboard?

I understand that this is a lot of code to skim through but I'm just plain stumped.

When you add a UI component in swing, you need to call the component's revalidate method for the changes to take effect.

Can't tell exactly what you are doing but I'm not sure you should be continually removing/adding individual components.
Maybe you should be use a Card Layout which will allow to you remove/add panels based on the specific function the user requests.

Can not fill an array in thread

This gui should draw moving images on frame panel called "system". But first of all i need to make those objects. Here i'm trying to add them to an array and use that array in other classes. But array keeps being empty!
I guess the problem is in declaring(bottom of the code). There is no exception thrown because I let other classes to execute only when this array(Planetarium) is not empty(it should work like that, because other moves depends on planets created(those objects)). But if it is empty that means nothing is declared...
What should i do if I want to fill an array in the thread executed in event listener?

EDIT: add linkedlist(still nothing after display) and moved declaration before infinite loop

You don't appear to have assigned these arrays anything so they should be null rather than empty.
The way you are using them a List might be better.
final List<Planet> planetarium = new ArrayList<Planet>();
planetarium.add(new Planet( .... ));
Planet p = planetarium.get(i);
for(Planet p: planetarium){
// something for each planet.
}
Note: you have to create an array before using it and you have know its length which is fixed. A list can have any length, but you still need to create it first.

Look at the loop before:
Planetarium[i] = planet;
It looks like it will loop infinitely
for(i=0; i >= 0; i++)
i will alway be >= 0.
